Installation
Location and mounting
Rest the QC-300 on a flat, stable surface,
or bolt it to a stable surface from the bot-
tom using four 10/32 screws fastened in
the pattern shown at the right.
Power surge suppressor
Connect the QC-300 to power through a high-quality power surge suppressor. Surge suppressors limit the
amplitude of potentially damaging power line transients caused by electrical machinery or lightning. When
a surge suppressor is not used, power line transients can corrupt system memory or damage circuits.
Connecting axis encoders
Axis encoders are attached to interface connectors on the rear of
the QC-300. Many encoder interfaces are available to match
the wide variety of encoders that can be used with the QC-300.
The type of axis encoder connectors will vary depending on the
application. Encoder inputs are specified as analog or TTL at
the time of purchase and cannot be changed in the field.
1 Verify that the QC-300 is off.
2 Connect the axis encoders tightly to their
connectors. An axis label is provided near
each connector. Do not overtighten the connector
screws.
Encoder input parameters must be configured later using the Encoder setup screen. Please refer to
Chapter 11: Setup for details regarding encoder setup.
